Budget Modification Descriptions
-Power Supply upgrades/rebuild for both Digital and Analog Supplies
Replace stock rectifier diodes with handmade ultra low impedance custom ASi versions,
(removes grain and grit and improves speed), Replace main SMPS filter cap with a over sized
low impedance capacitor for more power storage and much better filtering (improves bass,
speed and overall resolution). Replace stock electrolytic capacitors with ultra fast, ultra low
impedance Rubycon caps (more speed, better bass, better control, better resolution), replace
internal AC high voltage input wiring with silver wiring. Replace stock IEC with 3prong IEC that
is cryogenic treated.
DEXA Clock Reference Clock Upgrade-
Replace stock clock oscillator that feeds the critical DSP circuits to the new ultra low jitter
DEXA clock. This lowers the phase noise (jitter) to ultra low levels (under 2 picoseconds RMS
!!!!) and allows the unit to perform to much higher standards, accurately retrieving more
information off the disc. More detail, better focus, better bass, voices and instrument locations
and overall resolution is the improvements in this critical mod upgrade.
Analog Output Stage Parts Upgrades-
Replace stock interstage opamps with the best sounding ones on the market made by
national semiconductor for much cleaner, more resolute and dynamic performance. Replace
all voltage rail decoupling caps with ultra low impedance Rubycon capacitors. Add set of very
high quality Vampire RCA jacks to rear and wire in with silver wire.

Analog Output Stage Rebuild w/signal coupling transformers & Part Replacements
This is the most critical of all the modifications that are performed in this machine. The stock
output stage is chalk full of signal capacitors, resistors, transistors, etc.. We completely
disconnect this output stage and rebuild it with a optimal sounding output stage consisting of
very high quality audio signal coupling transformers. This is the largest improvement that can
be done in the entire unit. The very high quality transformers provide galvanic isolation in the
signal path (which blocks HF noise being generated by other component down the signal
chain) and gives a means of providing a ultra simple, no-capacitor-in-the-signal-path type
output that is sure to stun and please you to say the least. In this mod as well, we replace an
abundance of voltage rail capacitors for the DAC chip area to the ultra fast Rubycon
capacitors, and all wiring is Silver Wire. Add set of very high quality Vampire RCA jacks to
rear and wire in with silver wire. Now this player can outperform expensive flagship type units
on the market for a fraction of the cost! Now Music is so much quieter, cleaner, clearer, more
vivid,more resolute with no lack of dynamics! Much more music, emotion, and drive over stock.
